Physiological and behavioural indicators for fish welfare assessment in aquaculture and fish capture

Tildelt: kr 12,1 mill.

Seafood consumers are concerned about animal welfare and recent white papers states that Norway should take a leading position to ensure acceptable animal welfare standards as basis of an sustainable and ethical aquatic production. Institute of Marine Res earch (IMR), Bergen has a leading role in advising the Norwegian Ministry of Fisheries and Coastal Affairs on fish welfare issuses and has responded by making fish welfare one of 3 focus areas for future aquaculture reserach. However, fish welfare researc h is a new dicipline, and both research methods, infrastructure and basic knowlegde needs to be further developed to improve scientific risk analysis and advise on management strategies in this field. The current SIP proposal will complement and strenhgt en current research by increasing IMRs physiological and behavioural toolbox relevant for welfare assessment and include welfare questions related to fish capture. This will include: ·Develop existing physiological and behavioural models to study performa nce and welfare of fish in complex environments ·Develop experimental facilities tailored to address challenges about basic stress physiology, capacity for aerobic respiration and buoyancy control of target species in fisheries and aquaculture ·Explore the association between physiological stress response and cognitive interpretation of stressors ·Use these facilities and basic knowledge to address questions related to swimming endurance, exhaustion and forced decompression during fish capture and welfa re consequences for fish escaping the fishing gear or left to recover in net cages (CBA) ·Test model-generated hypotheses about the performance, stress response and welfare of conditioned or unconditioned hatchery reared fish in time varying environmenta l regimes and effects of new feed sources in controlled tank studies. ·Develop operational protocols for assessment of welfare and responsible handling and farming of cod
